So today i was on my way home and my car shut off while at an idle speed... when i tried to start it, it would crank but not start so i pumped the gas at the same time and it started, when i put the car in drive it automatically shut off again. so i disconnected the maf sensor and it started and didnt stall... what could be causing this nagging issue??? i replaced the fuel filter and the crank sensor...could it be a dirty maf sensor?
